Raised Installations
The fireplace may be raised by building a platform of sufficient strength to
support the fireplace and pipe. When building a raised hearth extension,
please see the note below regarding height of the fireplace in relation to
the thickness of the hearth extension material.
Hearth Extension Considerations
It is IMPORTANT to note that there is a 1” space between the base of the
fireplace and the bottom of the fireplace face. See Page 13 for hearth
extension requirements. This space will allow a 7/8” (22 mm) thick hearth
extension (including backer board if desired). Should a hearth extension
thicker than 7/8” (22 mm) be desired, the height of the fireplace must
be raised the thickness of that hearth extension less the 7/8” (22 mm).
For example, if a 2-7/8” (73 mm) thick cultured stone is to be placed
on the floor to serve as the hearth extension, then the fireplace must be
raised 2” (possibly using 1/2” (13 mm) plywood over 2 x 4’s laid flat)
to accommodate the 2-7/8” (73 mm) stone. It is important to note that
if the fireplace is raised, then it is necessary to raise the height of the
header above the stand-offs an equal amount.
